Measures to satisfy standards

This chapter explains the measures to comply with the EMC Directive, UL/CSA Standards, etc. by
introducing examples.
9. 1

How to deal with CE marking

In Europe, the EMC Directive and the Low Voltage Directive, which took effect in 1996 and 1997 respectively,
made it obligatory to put the CE mark on every applicable product to prove that it complies with the directives.
Inverters do not work alone but are designed to be installed in a control panel and always used in
combination with other machines and systems for the purpose of controlling them. So they themselves
were not considered to be subject to the EMC Directive. However, the component also became subject to
law with the enforcement of the new EMC Directive 2004/108/EC in 2007. For this reason, we put CE mark
on all inverters in accordance with the EMC Directive and the Low Voltage Directive.
The CE mark must be put on all machines and systems with built-in inverters because such machines and
systems are subject to the above directives. If they are final products, they might also be subject to the
Machinery Directive.
It is the responsibility of the manufacturers of such final products to put the CE mark on each final product.
In order to make machines and systems with built-in inverters comply with the EMC Directive and the Low
Voltage Directive, we recommend the installation method of inverters and measures for EMC Directive
described in this instruction manual.
We have tested representative models with them installed under the environment described later in this
manual to check for conformity with the EMC Directive. However, we cannot check the inverters under
your operating environment. EMC varies depending on the composition of the control panel with a built-in
inverter(s), the relationship with other built-in electrical components, the wiring condition, the layout
condition, and so on. Therefore, you need to verify yourself whether your machine and system conforms to
the EMC Directive.
9. 1. 1

Compliance with EMC Directive

The CE mark must be put on every final product that includes an inverter(s) and a motor(s). This series
of inverters are equipped with an EMC filter and complies with the EMC Directive 2004/108/EC if wiring
is carried out correctly.
The EMC standards are broadly divided into two categories; Emission and Immunity, each of which is
further categorized according to the operating environment of each individual machine as shown in the
table below. We consider that the tests required for machines and systems as final products are almost
the same as those required for inverters.
